will an rv-8 with 180-hp-fixed ptich prop operate from a 1300' grass runway at 850' elevation??
The -8 will, but can you, is the blunt answer. You certainly can with enough training and practice, if necessary.
I have operated a Supercub and a -9a out of one way 1020' (130' asl) with poor approach and felt quite safe. The max I ever use is about 75% of it.
When my -4 is finished and I have learned to land it, I will operate that there as well. I will not bring it into my strip until I can repeatedly land it over and over in a defined subsection of another local runway I use for comparison.
I discarded building an -8 because of runway length, but with an extra 280' I would not be concerned, since VANS ground role number is only 50' different from the -9, and their numbers seem to be accurate. [One health warning. I have not run the performance calculation on the effect of 1300' at 850' .v.1020' at 130'!]
My tips are:
- practice and practice and practice elewhere 'til it is not challenging.
- compare the GPS with the ASI every landing. You need to know if you have a local tail wind component, and do something about it.
- build it lite.

PS The issue is all about landing. Takeoff is a far more repeatable operation.
